Abstract


This article substantiates the relevance of research, the combined use of various paleontological methods, in particular, floristic and palynological, along with lithofacies and field geophysical data, to determine the oil and gas potential of the Jurassic deposits of Ustyurt, where it is necessary to create a reliable stratigraphic scheme, which is impossible without a detailed study of paleontological remains. For this purpose, complexes of spore-pollen and plant remains were studied by area Saamskaya-1p, Arka-Kungrad-1p, Muynak-1p, Northern Aral-1, Aral-3, Akchalak-4, East Berdakh-7, Akchalak-13, Shakhpakhty-1p, Northern Koskala-1, Kyzyl-Shaly-1p and others. The main types of sections were attributed by many lithologies and fishermen to the Lower Jurassic deposits. On the basis of spore-pollen analyzes and the study of plant remains, the age of the exposed rocks is dated as Middle Jurassic. Biostratigraphic subdivision of Jurassic deposits according to plant imprints and spore-pollen complexes in the Ustyurt region is developed on the basis of small stratigraphic units, such as a layer, a reference horizon, a suite, which meets the requirements of the international stratigraphic code (ISC).

Key words:

stratigraphy, Jurassic deposits, Ustyurt oil and gas region, hydrocarbon raw materials, paleontological materials, geophysical data, well, interval, formation
